It's these sorts of reasons that I am highly suggesting removing support for ePub.

This plugin creates a totally standard compliant ePub. There are no reason for removing ePub support from this plugin, except personal dislike. And since using or not using this plugin is just a matter of personal choice...

Furthermore, removing soft hyphens is just a snap.

Just a device compatibility list could be a reasonable suggestion (and people are already reporting successes and failures).
